My OCD tells me I’m a bad person all the time and it’s exhausting.

If I have a different opinion than somebody, my brain tells me I’m a bad person. If I don’t let people walk all over me and treat me badly, I’m a bad person. If I defend myself, I’m a bad person. My brain constantly tells me I’m bad and I have to monitor what I say to make sure I don’t ‘slip up’. If I’m not feeling very social in a class and I put headphones on, my brain says I’m ignorant and rude. It’s so exhausting. Any advice?
